Problem with LCD Shield DFR0009
Omikron81 2013-11-10 02:53:43 3935 Views3 Replies Hi there,
I got the LCD shield plugged on top of my Uno and everything works fine.
I now wanted to adress a relay shield via digital pin 13, with the wire plugged into the lcd shield where pin 13 should be "routed" through. On the Uno I can see that Pin 13 is adressed correctly, as the onboard LED lights up just fine, but the wire in the lcd shield gets no signal whatsoever.
I've tried using all pins the LCD doesn't use but to no avail.
Is there a problem with my shield or am I doing a mistake somewhere? I just can't figure it out.

As the hardware of the module is well, could you also attach your sketch?
It is a little strange, as you said "that Pin 13 is adressed correctly, as the onboard LED lights up just fine, but the wire in the lcd shield gets no signal whatsoever."
The led on board is connect to pin 13 internal. If the led is fine, pin 13 should get the same signal.
And the PINs on the lcd shield are different to the arduino board . It only has D13, D12, D11, D03, D02, D1, D0 Grey.CC

I could lay out the different shields on a board and connect them seperately with wires and it will work but as soon as I plug the LCD on top of my Uno no signal reaches the top of the LCD's pins.
I liked the design with stacking the shields as it saves lots of space but that doesn't seem to work out then.
Trying to take a photo tomorrow. Omikron81

Could you attach a photo about hardware connection?
Have you tried to connect your relay shield with arduino directly, without using lcd shield.? Does it work? Grey.CC
